20 & single

So I am newly 20 years old and have been single for all the years that I have been alive. I have a crush on a guy and have tried to get him to notice me by flirting, talking... unfortunately (not really aha) drunk lap dancing him... and even asking him out for coffee/tea. nothing is working.
I am also 2 years without some attention and currently have the opportunity to hook up with someone. I really want to but I also want to wait so I don't risk anything.
Idk what to do. My heart and head are telling me one thing, but my body and head is telling me another.
